Study Notes
Coordination in Compounds
- Coordination is the process of binding ligands to a central metal atom/ion to form a coordination compound.
Ligands in Coordination Compounds
- Ligands are ions or molecules that donate one or more pairs of electrons to form a coordinate covalent bond with the central metal atom/ion in a coordination compound.
- Ligands can be neutral molecules, anions, or cations.
Transition Metal Complexes
- A key characteristic of transition metal complexes is that they often exhibit vibrant colors due to the absorption of light by the metal ions, leading to electronic transitions between the d-orbitals.
- Transition metal complexes often exhibit magnetic properties, with some being diamagnetic (repelled by magnetic fields) and others being paramagnetic (attracted to magnetic fields).
